T S U B A K I D R I V E C H A I NRoller Chain ConstructionBefore Use For Safe UseStandard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling1. Basic Structure (Photo: RS Roller Chain)Offset pinBasic Three DimensionsThe pitch, roller diameter, andinner width of the inner linkare considered the basic threedimensions of a roller chain.When these dimensions areidentical, a roller chain andsprocket are dimensionallycompatible.Cotter pinSpring clips, cotter pins andspring pins are essential partsthat prevent connecting platesfrom falling off, maintainingthe strength of the chain itself.Always install these parts.*Slip FitWhen the shafts and holes arefitted together, there is acontinuous loose fit. This is afit where the range of tolerancefor the hole is larger than therange of tolerance for the shaft(pin or bush).*Press FitWhen the shafts and holes arefitted together, there is acontinuous interferential fit. Thisis a fit where the range oftolerance for the hole is smallerthan the range of tolerance forthe shaft (pin or bush).Slip fitPlateOuter linkRollerdiameterOffset linkInner linkPitchConnecting linkChainWidth between inner link platesThe plate bears the tension placed on the chain. Usually this is a repetitive load, butsometimes it is accompanied by shock. Therefore, the plate must have not only great statictensile strength, but also must hold up to the dynamic forces of load and shock.PinPress fitPress fit*2Press fitSlip fit*1The pin is subject to shearing and bending forces transmitted by the plate. At the same time, itforms a load-bearing part, together with the bush, when the chain flexes during sprocketengagement. Therefore, the pin needs high tensile and shear strength, resistance to bending,and sufficient endurance against shock and wear.BushPinRollerBushConnecting link plateSpring clipInner linkInner plateOuter plateMiddle plateSingle-strandouter linkMulti-strand outer link(Double-strand shown here)chainThe bush is subject to complex forces from all parts, especially from the repetition of shockloads when the chain engages the sprocket. Therefore, the bush needs extremely high shockresistance. In addition, the bush forms a load-bearing part together with the pin, and as suchrequires great wear resistance.RollerThe roller is subject to impact load as it strikes the sprocket teeth during chain engagementwith the sprocket. After engagement, the roller changes its point of contact and balance. It isheld between the sprocket teeth and bush, and moves on the tooth face while receiving acompression load. Therefore, it must be resistant to wear and still have strength againstshock, fatigue and compression. RS11 / 15 / 25 / 35 do not have rollers.Roller LinkTwo bushes are press fit into two inner plates, and rollers are inserted to allow rotation aroundthe outside of the bush. This is the same for single-strand and multi-strand chain.Outer Link and Middle PlateThe pin link consists of two pins that have been press fit into two outer plates. With multistrandroller chain, a middle plate is added to the pin link. The middle plate is slip fit forStandard RS Roller Chain and press fit for SUPER Roller Chain.11
T S U B A K I D R I V E C H A I N2. Assembly PartsRoller Chains are usually made up of a number of connected links in an endless formation, or used by fixing the chain ends, butthe need for connecting links will eventually arise. Although offset links can be used when there are an odd number of links inthe roller chain, please use a design that requires an even number of links as much as possible.2.1 Connecting LinksM-type Connecting linkClip typeOuter plateConnecting link plate(RC-processing)Cotter pin typeCotter pin typeMulti-strand (Double-strand shown)Outer plateConnecting link plate(RC-processing)Spring pin type(RS240 only)Connecting link plate(RC-processing)F-type Connecting linkPin Pin Middle platePin Pin PinClipCotter pin1-Pitch Offset Link (OL)Single-strandOffset link plateMulti-strand(double-strand shown)Cotter pinSpring pin2-Pitch Offset LinkSingle-strandMulti-strand(double-strand shown)Offset link plateSpring clipOuter platePin / Connecting ConnectingChain type Connecting link type Notelink plate fitting link plate fasteningRS Roller ChainLambda ChainSUPERRoller ChainSUPER-HRoller ChainHeavy DutyRoller ChainOther rollerchains in catalog2.2 Offset Link1-Pitch Offset LinkFor RS35 to RS60 offset links, allow for a20% reduction in kW (35% less for RS80 toRS240) and 35% less maximum allowableload (same for RS80 to RS240).M-type connecting linkCode: CLF-type connecting link *Code: FCLM-type connecting linkCode: CLM-type connecting linkCode: MCLF-type connecting linkCode: FCLF-type connecting linkCode: CLF-type connecting linkCode: CL M-type connecting linkCode: CL2-Pitch Offset LinksThe pin and offset link plate of a 2POL is pressfit and is fastened by a rivet.

The connecting link plate fastening method for each chain size is indicated in the dimension tables and the table notes.2. The color of F-type connecting links for RS Roller Chain and RS-HT Roller Chain marked with * is black.Remark: Ring Coin (RC) ProcessingThis <strong>Tsubaki</strong> original processing adds an area of plastic deformation around pin holes to generate residual stress around the holes.4-Pitch Offset LinkNote: See the dimensional tables for roller chain types and sizes suitable for offset links.Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling See the notes for BS/DIN Standard RS Roller Chains section.12
